METALLIC BASEBARD STRUCTURE.

Tov all whom, it may! concern.'

Be it known that I, Gnouen A. KNAW. a citizen'ot the lflnited States,residing' at Chicago, in the countyotl Cook and State of Illinois, haveinvented certain new and uset'ul Improvements in Metallic BaseboardStructures, of which the Jfollowing is a. specification.

The invention relates to improvements in metallic base board structuresfor buildings.

Une of the objects ot the invention isV to generally improve devices ofthe. character to be described. i

Another .object is to provide a composite metallic, wall base boardwhich will automatically compensate for settling of the floor toprevent'unsightly cracks or gaps between the floor andthe. joininpy partet the base board structure.

Another object is to provide a structure that mayeasily .and quickly beapplied; that is tiexible'to readily meet any inherent ii regularitiesin the ioor or the Wall: that is inexpensive to manufacture, and that iscapable of receiving;r a smooth, even linish resenibling wood.

Other objects and advantages of the in vention will readily appear.

Fig. l shows the structure as it appears at an inner corner and at anouter projecting corner of a room.

Fg 5 is a section taken' on line 5--5 of In all the views the Santereference characters are employed to indicate similar parts.

In the drawings l() 'represents the floor ot a room and ll and 12-represent fragments ol' avertirfal lwall at substantial riglllt anglesto each other.

The major member ot the metal base board -ronsists of the face plate '13haring an incurred top edge lilwith a salient edge l5 rest-ing againstthe `presented surface of the vertical Wall. The lower edge of the taceplate 13 is acutely iuturned to provide a tlaugelt, the. salient edge ofwhich rests of these screws may e countersunlr into the surface ot theplate 13 by indenting the plate and the depressions due to this `ett-eetrnay be filled with any suitable plastic ina te* rial, such as smoothon. or the like. so

that the surface will thereby be made uniQ torni with the remainingfront portion of the plate to receive a finish Without exhibN itingablemish.,

At the inner cerner 18 of angularlv related -walls 11 and 19 there is abra et er corner piece 19, angular in cross section and having ribs 20to space it from the respeetive walls a suitable distance.- so thafthefrontl of the plate 13 will be flush with the vertical inner surface etthe corner piece. The members of the bracket 19 Ycontain rab betel oneach vertical edge to bring' the' plate 13 luslr with the surface andscrews el are inserted thru openings 22 made in tl: ner xueinbers toreceive them. Then brackets i9 join the plates 13 in i; lines :213. Thecorner brackets lil are also provided witha spaeingphub :la which. naarconveniently surround screws 2l to sp z y tbe outer surface ofthebracket. the proper distance trom the `walls 11 and l2.

n outer corner bracket i5 is also .prou rided with rabbets 33 to receivethe vertical. 4edges ol the adjacent plate l-l and crews 2T .pass thruthe plate and thru per Iliade in the flanges ot the brin-lard, asuitable portion ot the Walls Vli and l?. i the ease may be. Thesebrackets also have spacing` ribs their the plates 13 with the brackets"ltr and have been placed in contact 'with the vertical wallsl ll and l2,in the manner dcserilvcd, the lower edges of the brackets and the platesdo not extend ,quite 'to the l,tloor liuc :md5therefore. to-ronipletethe linish a curved cove :drip 2C is placed below ille tace plate. Therote corner strip when extended alone the lloor line .is preferablycuryed. as shown more clearly in Fig. il. and is cured at intervals tothe floor by means el' `screws 27. The lower edge Q() of the curved covestrip rests upon the floor lt), while the upper edge 29'overlaps thelower edge of the tace plate 13 above vthe flange 16 to permitrelativevertical movement of the tace plate 13 and the cove,strip, so that'intimate contact is always preserved between the mem-A cleaning and forsanitary precaution.

A preferable cove corner member 30 is located below the member 19 andbasan overlapping edge 3l in horizontal alignment with the upper edge 29of the cove strip 26. The corner member 30 has a. rabbet portion 33underlying the cove strip 26.0n both of its sides, so that the member 30cannot be removed after the cove strips have been held in position bythe screws 27. A similar bottom member is placedat\the bottom of thebracket or corner member 25 and has an upper edge 36 in the horizontalalignment with the upper edges 29 and 3l, respectively. The outer cornermember 25 is held in place by screws 37 that pass thru the face plate 13into a suitable support 38 let into the plastered wall.

From the foregoing description it will be manifest that the members 13and 26 may be separated to some extentand the overlapping at theirmeeting edges will automatically compensate for any vertical relativedisplacement thereof.

lThe members 30 and 35 will move coextensively with the curved covestrip 2G and as they overlap the relative members thereabove the sameeffect will be produced.

Having described .my invention what l claim as new and desire to secureby Letters Patent, is

l. A metal base board comprising a face plate for attachment to avertical Wall-@and a cove strip having its upper edge overlapping thelower edge of the plate and having its lower edge in Contact with afloor to compensate for relative vertical displacement of the membersand means independently of the plate to hold the strip in place.

2. A metal base board comprising a faceI plate for attachment to avertical wall having its; lower edge spaced away from the floor and acove strip having its upper edge overlapping the lower edge of the plateand having its lower edge in contact with a Hoor and secured to thefloor to compensate for relative vertical displacement of the members.

A. metal base board comprising a face plate for attachment to a verticalWall having its lower yedge spaced away from the floor and a cove striphaving its upper edge overlapping the lower edge of the plate and`l-raving its lower edge in contact with a floor, secured to the floor,to compensate for relative vertical displacement of the members and twopart overlapping corner bracket members at the ends of said plates tocontinue the respective surfaces around the corners.

4. A hollow metal base board comprising a face plate having an upperincurved horizontal edge and a lower inturned flan e With itsl salientedge in the same vertice plane and a concave cove strip overlapping thelower edge of the plate and having its lower edge in contact with theHoor and screws passing thru said strip and into the floor at suitableintervals.

In.. testimony whereof I hereunto subscribed my name.
